Hi Mark,

* This problem may be caused by wxPython being built/linking against  
older versions of libexpat than pyexpat is.
* A solution may be to do a clean build and install of both wxPython  
and pyexpat.  (libxml has been recently upgraded in version from  
2.6.28_0->2.6.28_1, perhaps causing your incompatible builds?)
* This bug is documented here:

* It notes that the problem is caused by version mismatches.  A  
solution that avoids the problem has been applied in 2.5, but not in 2,4
* Here are a couple of other references to the problem (without  
solutions)
